Fix a little error with the None auth type
Fix a little error with the None auth type

Ironic has a mode where it does not use auth, but we still funnel that
through the ksa admin_token type for consistency of code. The hack we
had to do that went too far and caused validate_auth to strip the fake
token we were adding.
